Title:
DISPLAY DEVICE AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/130759
Kind Code:
A1
Abstract:
A display device and a vehicle. Optical paths of different sub-imaging light can be changed by using a prism group (103, 803, 1003), an optical path structure is simple, a device reuse rate is high, and a picture of an image is basically crosstalk-free. The display device comprises: a projection module (101, 801, 1001), a deflection reflection assembly (102, 802, 1002), and the prism group (103, 803, 1003). The projection module (101, 801, 1001) is used for projecting a first channel of imaging light to the deflection reflection assembly (102, 802, 1002); the deflection reflection assembly (102, 802, 1002) is used for reflecting the first channel of imaging light to generate at least two channels of sub-imaging light, and respectively reflecting the at least two channels of sub-imaging light into the prism group (103, 803, 1003) at at least two angles; the prism group (103, 803, 1003) is used for enabling the at least two channels of sub-imaging light to be transmitted in different paths, and emitting the at least two channels of sub-imaging light.
